Glacialpower was kind enough to send over their 550W power supply, the GP-PS550BP. With an intelligent and silent design, it should provide great performance with some peace and quiet. I'll crack open the PSU to take a look inside as well to see what it's made of. With 550 Watts of power, it can power just about any mid-range PC you can piece together and possibly more.

The front of the packaging gives a quick overview of power supply.

On the back of the box you have the DC output load table and a bit more information.

The DC output looks to be sufficient.

The DC power chart on the PSU. I guess they don't want me to remove the cover.

The ATX 24 pin cable is nicely wrapped, while the other leads are not.

Here is a shot of P4 power plug and 24pin ATX power end. You may want to note that this psu does not come with a P4+ plug.

This PSU has two PCI-E 6pin plugs. With some of the high-end video cards requiring either two 6pin or one 8pin, you will need an adapter to get that done.

With the cover removed, you can check out the nicely sized aluminum heatsinks used for cooling.
